# Airplane displacement [closed]

An airplane maintains a speed of 693 km/h relative to the air it is flying through as it makes a trip to a city 766 km away to the north.

(a) What time interval is required for the trip if the plane flies through a headwind blowing at 36.9 km/h toward the south? Answer - 1.1675

(b) What time interval is required if there is a tailwind with the same speed? answer - 1.049

(c) What time interval is required if there is a crosswind blowing at 36.9 km/h to the east relative to the ground? answer - 1.105

I managed to get all the right answers, however I'm not sure what I did to do this and would like an explanation on it as well. Thanks!

Hi Julian - as I explained on your other question, this is a site for conceptual questions about physics, not general homework help. If you edit your question to ask about the specific physics concept that is giving you trouble, I'll be happy to reopen it. As always, see our FAQ and homework policy for more information. – David Zaslavsky Sep 10 '12 at 1:32
@DavidZaslavsky how could I reword this question then in order to get what I'm looking for? I already have the answer so I'm not looking for help getting the answer on here. I just want to learn how I would go about properly getting the answer since I pretty much randomly divided things to get the answer, but can't replicate how I got it again, and want to understand what I'm doing rather than guessing and checking. – Julian Sep 10 '12 at 1:43
If you really have no idea how to get the answers, then to be honest, this is not the place to look for help. You should read your textbook and ask for help from your instructors and/or your fellow students. Explaining how to do this problem starting from nothing takes several sessions of an introductory physics class, and it's not our place to go through all of that knowledge. – David Zaslavsky Sep 10 '12 at 2:07
